CUSTOMER CHALLENGE: How can we analyze the mayonnaise texture?

My questions are related to Mayonnaise, that are:

1. How can we analyze the mayonnaise texture?

2. At what temperature we should measure mayonnaise viscosity through offline Brookfield viscometer? (generally we cool mayonnaise from 29 degree Celsius to 25 Degree Celsius)

3. How can we reduce handling error for Viscosity measurement through Brookfield Viscometer?

BROOKFIELD ANSWERS: Thank you for your inquiry.

Viscosity measurement of mayonnaise has traditionally been accomplished with Brookfield T-Bar spindle and Helipath Stand accessory when using Brookfield viscometer with RV Torque Range. New methods allow for use of vane spindle with Brookfield DV3 Rheometer to measure the yield stress in mayonnaise as well as the viscosity.

Texture measurement of mayonnaise is performed with CT3 Texture Analyzer and choice of various fixtures, depending on the physical property of interest. The TA-STF measures spreadability. The TA-DEC measures extrusion. And the TA-MP measures consistency.

CUSTOMER CHALLENGE: When I perform multiple cycle tests, I don't see the same results in stand alone mode that I see when using the software, why?

BROOKFIELD ANSWERS: When running a test consisting of multiple cycles you will get three results in standalone mode. They are peak hardness (highest peak of all cycles), hardness of the last peak, and the standard deviation of all peaks. At this time, the TexturePro CT software only provides the hardness of the first peak and the average of all cycle peaks.

CUSTOMER CHALLENGE: We are occasionally asked, what is the safe temperature range for our texture probes?

BROOKFIELD ANSWERS:The answer depends upon which probe. Our plastic probes come in two types of material. They are clear acrylic and black delrin. The temperature range for each probe is as follows:

• Acrylic Service Temperature – (0F -150F)
• Delrin Service Temperature – (-40F to 185F)

CUSTOMER CHALLENGE: Can the CT3 be connected to a printer or an external computer via the USB or RS232 ports?

BROOKFIELD ANSWERS: No data comes out of either the USB or RS232 port in standalone mode. Data is only available at these ports when running with Texture Pro CT software. We occasionally field related questions whenever customers consider connecting to a PC and writing their own data acquisition software. This is impractical and should be discouraged.
